Tear Resistance Explosive Cartridges Application Cross Laminated
Film
Product Description:
What is cross laminated strength film?
It is a high-strength multi-layer composite film,It is made of HDPE
as the base material,
adding plasticizer, plasticizer, stabilizer, antioxidant, UV
absorber, toughener and other
additives through multi-layer co-extrusion blow molding into
embryos, and then by multiple
pull Stretching, then rotary cutting into a film substrate with a
horizontal and vertical distribution
of 45 °, and finally through cross-compositing. Due to its
cross-stacking structure is different
from ordinary single-layer or multi-layer film, it has the thermal
stability, dimensional stability,
two-way tear resistance, two-way uniform tension and high
elongation which are not available
in traditional films.
Why cross laminated strength film?
When conditions demand high-performance packaging, Cross Laminated
Strength Film
is your solution. Fungicides, pesticides, toilet bowl drop-ins, and
pool chemicals can be
packaged in confidence, with proven child-resistance, when you use
Cross Laminated
Strength Film. High-performance packages made with Cross Laminated
Strength Film
provide high burst strength, unbeatable tear-resistance, superior
moisture and chemical
resistance, as well as outstanding printability.
Cross laminated film is used in high impact resistant explosive
cartridges for form,
fill and seal (FFS) packaging of emulsion or water gel explosives.
Cross laminated film provides low elongation that assists in the
filling and production of emulsion
explosives at high fill temps without creating a baggy film on the
finished chub.
The finished chub remains rigid throughout the manufacturing and
transport process,
ensuring blast integrity on site. It also provides excellent
resistance to tear which protects the cartridge
from puncture during installation in a bore hole.
Because of Cross laminated film unparalleled strength, puncture,
tear and tear propagation resistance
in combination with high dimensional stability we are able to stand
up to the rigors of government and
military applications.
Advantages:
► Puncture Resistant
► High Thermal Stability: The ability to be used in any climate
because of cross laminated film's
ability to withstand temperatures ranging from -30°-80°C. Provides
a wide temperature filling range,
making cross laminated film the ideal material to pack explosive
gels and hot filled emulsions.
► Barrier against chemical migration
► Waterproof and Chemical Resistant: Barrier against water and
moisture. The closed tructure
(non porous, high barrier) of cross laminated film creates the
ideal material in which your
explosives are securely packed.
► High seal strength with polymer seams
► Minimal Elephant Footing: cross laminated film outperform other
films on site.
It drastically reduces chub or cartridge distortions when dropped
down the borehole.
